I think Keep it up is in the key of E minor.
The base note goes A - G - F# - D #
And You can work chords off that by just adding bar chords.

A G F# D#
just use same form of chord used with A for G and F#. I then used a bar chord with roots on the 5th fret( bare in mind I never got lessons so if what i am saying doesn't make sense please let me know)
I think that is basically it
